Common Questions
Is it a 1 stage or a 2 stage?
It tells you that it's a 1 stage on the side plate.
What is the size of the inlet valve?
The manufacturer should provide this info, including the size, type of fitting, and male/female.
I got a power converter that will be able to handle a load of 300 w, so I'm going to use it in Norway. How many watt is this pump?
The motor's rated power is 1/3 HP, but that's assuming that the motor was 100% efficient, which it isn't. The full load watt of that motor could be as high as 600 to 700 watt.
Which brand of oil is recommended by the manufacturer?
I don't believe they recommend a specific brand, just that it be vaccum pump oil, its sent with a bottle big enough to just fill it up, its a very thin oil, and I know Amazon offered a bottle at checkout but I haven't needed any additional oil as
What is the amplifier?
